Not too difficult, two rounds, case studies and behavioral questions. pharma focused cases. First round one case and one behavioral, second round was two consultants, case per each. Definitely practice a lot, know basics of your mental math, and also learn pharma/life sciences related cases and their frameworks.

Two rounds of 2 interviews each with 2-3 behvaioral questions and a case interview. The cases were very similar to each other and similar to those found online - new product/drug case, with questions like what experts to talk to, patient segments, and simple math.
